LONDON – Cult British singer-songwriter -- and the king of self-deprecation -- John Otway will screen Otway: The Movie, a documentary charting his own life and career that won't be finished until the day of the presentation.

Otway, billed as "rock and roll's greatest failure," will be in the auditorium of the Odeon Leicester Square on October 7 to watch the feature-length documentary.

While the audience watches the film, the movie team will be frantically editing the ending, which will include scenes of the stars, celebrities and Otway himself arriving on the red carpet less than two hours earlier.

The film and event backers claim it will make for the "one of the most intense and exciting cliffhangers in cinema history."

No one, not even the director, will know in advance what the ending will look like.

Otway, who will 60 on October 2, has enjoyed an eccentric career "driven by ambition and an unshakeable belief in his ability to succeed against the odds."

The movie documentary begins with the singer’s first taste of chart success in 1977 with "Really Free," and TV appearances on the BBC’s Top of the Pops and The Old Grey Whistle Test music shows.

Over the next 30 years, the man billed as "punk rock’s underdog" has faced a catalog of spectacular failures as his ambitions have become bigger and bolder including a world tour with his own jumbo jet.

Told with warmth, honesty and self-deprecating humor, the film promises a warts-and-all lesson in how to survive in showbiz and is put together by Otway himself.

For his 40th Birthday, Otway played the Royal Albert Hall with a full orchestra.

For His 50th Birthday, he achieved his first top ten hit and played the London Palladium.

And now for his 60th Birthday, he’s set to premiere his first film at the largest cinema in the U.K.

As with Otway's last major project -- where his fans chose produced and marketed the single "Bunsen Burner" to get it into the Top Ten and on to Top Of The Pops – Otway: The Movie is a project funded, produced and directed by the singer's following, which includes a number of artists, directors and industry professionals.

Negotiations are ongoing with sales agents and distributors for UK and global rights.

Following its screening Oct. 7, the project will be shown at international festivals before a planned full release in 2013.
